BRONZING-IVICHINE SPECIFICATION forming' part of Letters Patent No. 695,157, dated March 11, 1902.

Application filed July Z4, 1901. Serial No. 69,576. (No model.)

To all whom it may concern:

Beitknown thatI, GEORGE KLAIBER, acitizen of the United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented new and useful Im'- provements in BronzingMachines, of which the following is a specification.

My invention relates to machines for putting bronze-powder upon lithographie work; and the object thereof is to provide for the removal of the unused bronze from thelmachine without stopping the machine. I accomplish this object by the mechanism described herein, and illustrated in the accompanyng drawing, which is an end view of a bronze-machine, partly in section, with my improvement applied thereto.

In the drawing, A is the frame of the inachine, in which is mounted the usual sheetcarrying wheel B, having gripper-lingers O, bronze-distributing brush D, dust-rollers E F G, and burnisher H.

, .I .I are Scrapers to remove from dusters E and F any bronze Which might cling to the surface of said dusters. to polisher H for a like purpose, and L is a brush applied to Wheel B for a like purpose.

The paper to be bronzed is fed into the machine over feed-board M onto the carryingwheel and is held thereon by the gripper-fingers C n the usual manner. As the sheet of paper passes along bronze is fed upon it in the usual manner from bronze-fountain N by furwheel O, which revolves in the bottom thereof, and it is spread by brushes D. The surplus bronze is removed from the surface of the paper by the rapidly-revolving dusters E, F, and G, which revolve in the direction of the arrow and blow the loose powder off the paper. In the machines with which I am acquainted this surplus bronze settles on pans or shelves below the duster-rollers and piles up between them and the casing of the ma! chine. As soon as a suflicient quantity of surplus bronze has collected back of the duster-rollers, so thatit contacts with their surface, it must be removed to prevent its passing on out of the machine on the finished sheet, and thereby waste the bronze. The removal of this bronze necessitates the stopping of the machine, as the bronze-powder is K is a brush appliedv very light and would fly all over the press room if the doors were opened while the duster-rolls were in motion. To render this stoppage unnecessary, and thereby save the operator time, I turn the ou ter end of the bronzereceiving pans P, which are under the two lower duster-rollers, below the horizontal position, and cut a slot R in the casing S of the machine where the ends of these pans join the same. On the outer side of the casing I attach a receptacle T, provided with drawers U, into which the bronze will fall from the pans. In close contact with the casing of the machine I provide slide Y, having slots W, which register with the slots in the casing when the drawers are ready for the reception of bronze. This slide can be pushed downward so as to close the slots in the casing, so that the drawers may be re- ,claim as new, and desire to secure'by Letters l. A bronze-holding attachment for bronzin g-machines, comprising a receptacle afliXed to the machine in the rear of the duster-rollers; drawers in said'receptacle, the rear end of the top of which is below the top surface of the rear end of the pans under the dusterrollers; slots in the casing of the bronzing machine, above the rear end of the pans under the duster-rollers; and a movable slide provided with slots to register with the slots of the casing, and adapted to be moved to close the slots in the casing.

2. In a bronzing-machine, means to remove the surplus bronze from the machine while in motion, comprising slots in the casing above the pans under the duster-rollers thereof; a slide adapted to close said slots, when desired; a closed receptacle having removable drawers, aflixed to the casing at said slots, substantially as described herein.

In a bronzing-machine, means to remove the surplus bronze from the machine while in IOO motion, comprising a closed receptacle nfxed In Witness that claim the foregoing have to the casing of the machine in the rear of the hereunto subscribed my name Ithis 17th day 1o (luster-rollers, having means to clean out the I of July, 1901.
